It is likely your monitor's backlight has gone out. On LCD monitors like the one in your laptop, the Liquid Crystals can only be seen clearly when excited by light. This is not a user-servicable part and typically requires replacing the entire LCD monitor. I would recommend a new PC because of the high cost of replacing this part. Or, continue using an external monitor.

What ??? is this a desktop or laptop ?
Do you mean you cant see yout laptop screen ?
The display on your laptop is the interface through which you interact with and control your computer.
If it is not working, your laptop will become virtually impossible to use.
A laptop is a computer, and like all computers is subject to both hardware and software problems that may affect the display.
Before taking your laptop in for repair or getting rid of it, you should first check the display yourself to see if it needs to be replaced.
Check the laptop's battery and power cord.
If the laptop is out of power, the display will not work.
This usually happens if the power cord is unplugged and you were unknowingly running your laptop on battery power.
Check to make sure the power cord is plugged in and that the laptop has power.
Many laptops also turn off the display if it is being powered by its battery after a period of nonuse. Touching any key will usually turn the display back on if the battery is not drained.
Restart your computer. If a software program is stuck or malfunctioning, it may cause your display to stop functioning.
Press and hold the "Power" button on your laptop to reboot your computer.
If the problem was a malfunctioning program, the display will turn on after the computer restarts.
Check the brightness level of the display.
If the level is too low, the screen will appear dark.
The brightness controls are usually located on two function keys, such as "F9" and "F10." Look for sun or light icons on the keys.
Press the key with the larger icon to increase the brightness level.
Alternatively, on some laptops hold the "Fn" key while simultaneously pressing the "Up Arrow" key to increase the screen brightness.
Check the display closed switch.
Many laptops have a small button that senses when the LCD screen is closed and puts the laptop in sleep or hibernation mode.
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
http://www.kitchentablecomputers.com/static.php - rules
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
Some of the below steps recommend removing physical parts within the computer.
While in the computer it is highly recommend that you be aware of ESD and its potential hazards.
Check your RAM.
The RAM is located in the middle of the motherboard.
There are tabs that you can push to release the RAM.
Remove it and put it back in place until the tabs pop out.
Loose RAM can cause your computer not to start properly where you want to see a video signal.
Remove the memory modules from their slots.
Take the opportunity to clean the slots on the motherboards and the memory module connectors.
Use compressed air to blow dust away and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.


Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of minutes.
If reseating the memory did not resolve the issue try swapping the location of the memory.
Make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free
If the switch gets clogged with dirt, it may get stuck in the closed position.
This will result in dark display even when the lid is open.
The switch is usually located near the hinges of the lid. Spray the switch with a can of compressed air to loosen the dirt so that it will resume its normal operation.
Plug an external monitor into your laptop.
If the problem is not software related, the external monitor will display the laptop's screen.
Connect the monitor by plugging the cable into the VGA, HDMI or DVI port on the laptop.
Press and hold the "Fn" key while simultaneously pressing the "F8" key.
The video output will be directed to the external monitor if there is a hardware problem.

Screen on ma2a gateway doesn't turn on. Is it the video card?


Borrow a monitor and plug it into the VGA port. That might tell you whether the graphics card is bad.

How can I dim my screen?


Locate the Fn (Function) key on your keyboard. It may be on the bottom left side with dark blue letters. Locate the two "brightness" keys near the top of the keyboard. These will be in the "F" keys, possibly if F6 and F7. They should have little sun pictures or something similar to indicate brightness. Hold down the Fn key while pressing F7, or whichever "F" key your laptop uses to increase brightness. Tap F7 repeatedly until you reach the desired brightness. Fn must be held down as you continue to tap. Hope this helps.

Too bright


Open Power settings, dim display. I'm sure there is a brightness button on the monitor, sides or a Fn key. You can find the user manual here: http://us.acer.com/ac/en/US/content/support OR http://acer.custhelp.com/app/answers/detail/a_id/522/kw/Dim%20display/sno/1

I have an Ativa monitor M22HZR and the brightness is stuck. It's very bright and the controls won't allow me to dim it. What is the likely cause and what's the best way to handle it?


Most likely the reason is a faulty button that makes contact all the time. Open the monitor, check the buttons on the control board with multimeter and replace the faulty button. It have to be a button with + or > mark on the monitor's body.

Maybe the display brightness is low. Go to Control Panel and check somewhere. Also, look for a brightness key. My F7 and F8 have brightness up/down in rectangles.
Press the 'Fn' (Function) key and press the brightness up key. You're up and ready. Go, enjoy!

Acer aspire 5043wlmi laptop starts but know function of lcd but works on desktop monitor


The computer's power management system automatically dims the screen when using battery power, which is one of the power-saving features.
To adjust the brightness:
  • Hold down the Fn Key located at bottom left of your keyboard next to the Ctrl key, and adjust the screen brightness using the left/right arrow keys located at the bottom right of the keyboard.
If that's not it then

A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure. If your still under warranty then I would get Acer support on the phone and see what they can do.
An Inverter converts direct current (DC) to alternating current (AC).

I have hp pavilion dv6226us and when booted up the screen stays dark. You can see display only if you shine a light onto the screen. I tried to turn up the brightness and did't have any luck.


The VGA card or the VGA driver is not properly installed,perhaps.Try reinstalling the driver.
If you suspect the monitor brightness controls then try fiddling with them untill the brightness is good enough.
Check monitor cable also(VGA).
